This section describes the system model and the considered parameters of the transmitter, channel, and receiver of figure 1in addition, it gives a brief presentation of the underlined algorithms for the iterative demapping and decoding. The iterative krylov subspace solver does not require an expensive decomposition of the system matrix, but instead uses a sequence of matrix vector products to iteratively get a good approximation of the solution of the linear system. On the performance of iterative demapping and decoding techniques over quasi-static fading channels w r carson, i chatzigeorgiou and i j wassell. This paper presents a novel decoding strategy, called combined iterative demapping/decoding (cidd), for coded ultra wideband impulse radio (uwb-ir) systems from the viewpoint of coding, coded uwb-ir systems can be viewed as a class of serially concatenated coding, because channel encoder and pulse mapper in the uwb-ir systems plays a role of . In this paper, we have carried out an extensive study on phase-shifted superposition mapping (psm), particularly on its behavior in the scenario of iterative demapping and decoding it is shown that psm is a quasi-bijective mapping scheme and provides no rate limit in a coded system.
A method and apparatus for iteratively decoding a multilevel modulated signal in which the soft output information of a channel decoder is fed back and utilized by a tailored soft demapping device in order to improve the decoding result by further iterative decoding steps. Modelling the frame error rate for iterative demapping and decoding techniques over quasi-static fading channels of the iterative demapping and decoding system. Performance in iterative decoding/demapping however, a complete analysis of the itera- tive process is still lacking, and convergence of the procedure has not proved in general. As basic modulation technique we apply ofdm complexity like iterative detection, demapping, and decoding to mitigate the interference in both cases .
A method of joint equalization and decoding for block transmission with coding across blocks is presented we apply interleaving for iterative demapping, in . Iterative decoding and phase noise tracking for high-order method is integrated with a coded modulation system with iterative demapping and decoding it is shown . Iterative receiver design is a 2007 engineering book by henk wymeersch published by cambridge university press the book provides a framework for developing iterative algorithms for digital receivers, exploiting the power of factor graphs. Thus, iterative decoding is suitable for application, in particular, to the european wireless digital cellular standard gsm with the equalizer performing the inner decoding step and the decoder providing the outer decoding step. Obtained with iterative demapping and decoding in this paper applying bayes’ rule and assuming statistical independence as joint iterative equalization .
